Current activities
in
optoelectronics and nanoelectronics
My R&D activity
started at Vrije Universiteit
Brussels, under the ERAMUS Program on holographic optical elements
aberration correction with an intermediate computer generated hologram.
After completing the degree in Physics at the FCUP I joined to
FCUP/INESC Optoelectronics Centre to work on integrated optic
devices more specifically on modeling of polymeric passive
integrated optical component for wavelength division multiplexing. This
research was the basis of my master thesis in the context of the Master
on Optoelectronics and Lasers. The R&D activity continued with the
study of the optoelectronic
applications of resonant tunnelling diodes
(RTDs) at the University of Glasgow in joined PhD program with the
University of Porto. The intellectual property generated during the PhD
was patented and latter licensed to Essient Photonics Ltd, a spin-out
from Glasgow University, launched in 2002.
Presently, my R&D activities comprise the design, fabrication and
characterization of optoelectronic devices and circuits. The work is
focused on the development of new optoelectronic
circuit functionalities based on negative differential conductance
devices and includes hybrid and monolithic
integration of Resonant
Tunnelling Diodes (RTDs) with laser diodes and
with photo-detectors.
The main drive is the study of novel non-linear optoelectronic
integrated circuits with potential use in future chaos based
communication systems and RF-optical-RF interfaces for pico/femto cellular networks.
Other interests comprehend terahertz technologies for communication
systems and remote sensing.
